Blind Date (Deadly Seduction) (1984) [Hooker]: Dissected (off-screen) with a scalpel by James Daughton, after he ties her to her bed and draws a diagram on her chest to prepare her for "surgery."

Star Trek: The Next Generation: Cause and Effect(1992) [Deanna Troi]: Killed in an explosion (along with everybody else on board) when the Enterprise collides with Kelsey Grammer's ship; due to a time loop, this is repeated several times until Brent Spiner succeeds in preventing the collision. (Thanks to PortsGuy)

Star Trek: The Next Generation: Man of the People(1992) [Deanna Troi]: Is briefly clinically dead when Gates McFadden stops her vital signs, to break the connection from a being that was draining Marina's life-force and causing her to age rapidly. (Thanks to PortsGuy)
